CVE-2009-0125

DISPUTED NOTE: this issue has been disputed by the upstream vendor.
nasl/nasl_crypto2.c in the Nessus Attack Scripting Language library (aka
libnasl) 2.2.11 does not properly check the return value from the OpenSSL
DSA_do_verify function, which allows remote attackers to bypass validation
of the certificate chain via a malformed SSL/TLS signature, a similar
vulnerability to CVE-2008-5077. NOTE: the upstream vendor has disputed
this issue, stating “while we do misuse this function (this is a bug), it
has absolutely no security ramification.”
